“The Russian stuff can be had for 24 cents/round.”
the russian stuff is usually steel-cased, which is REALLY rough on firearms ... i wouldn’t shoot it in any decent firearm ...
Not all guns can shoot the Russian steel cased ammo reliably. I’ve had some that do, and some that get knocked out of service after around 40 rounds requiring a steel rod to knock them out of the chamber. Depends on your firearm. If you can run a few hundred rounds with no problem, don’t worry about it. I’ve also reloaded steel cased with no problems - just a few times though as they don’t stretch like brass. But in cases of emergencies... The steel used is MUCH softer than any metal in your chamber or bolt.
